Yes they do, like any other reputable trucking company. But they also use common sense in looking over a DAQ report, like not looking at the guy who has the same name, but different DOB or living in a different part of the country, etc.
ODFL is smarter than, say a FedEx contractor who doesn't know how to read or doesn't want to be bothered with sifting through a DAQ report. I'm not sure what company provides ODFL with DAQ reports, but they always have the accurate info needed.
